Research suggests that most mental health conditions have their onset in the critically social period of adolescence. Yet, we lack understanding of the potential social processes underlying early psychopathological development. We propose a conceptual model where daily-life social interactions and social skills form an intermediate link between known risk and protective factors (adverse childhood experiences, bullying, social support, maladaptive parenting) and psychopathology in adolescents – that is explored using cross-sectional data.

N = 1913 Flemish adolescent participants (Mean age = 13.8; 63% girls) were assessed as part of the SIGMA study, a large-scale, accelerated longitudinal study of adolescent mental health and development. Self-report questionnaires (on risk/protective factors, social skills, and psychopathology) were completed during class time; daily-life social interactions were measured during a subsequent six-day experience-sampling period.

Registered uncorrected multilevel linear regression results revealed significant associations between all risk/protective factors and psychopathology, between all risk/protective factors and social processes, and between all social processes and psychopathology. Social processes (social skills, quantity/quality of daily social interactions) were uniquely predicted by each risk/protective factor and were uniquely associated with both general and specific types of psychopathology. For older participants, some relationships between social processes and psychopathology were stronger.

Unique associations between risk/protective factors and psychopathology signify the distinct relevance of these factors for youth mental health, whereas the broad associations with social processes support these processes as broad correlates. Results align with the idea of a social pathway toward early psychopathology, although follow-up longitudinal research is required to verify any mediation effect.

Classification of mental disorders evolved greatly over time, as DSM and ICD dominated both research and everyday practice in the past decades. DSM-5 was planned to represent biological features of psychiatric disorders and include results of genetic and imaging studies in the criteria. Unfortunately, this goal couldn’t be fulfilled, since, although there were promising results, evidence wasn’t strong enough to fully support the biological background of the currently used diagnostic categories. One possible explanation for this discrepancy is that biological disturbances don’t represent the somewhat artificial categorisation of these disorders. Many of the leading symptoms in psychotic disorders are nowadays considered as lying on a spectrum, such as autism, affective and psychotic spectrum disorders. Despite that, DSM-5 still describes schizophrenia, schizoaffective disorder and bipolar disorder as separate entities, however there can be major overlaps in the leading symptoms, moreover symptoms are not necessarily stable over time and can show fluctuations. It should be mentioned though that subgroups of schizophrenia in DSM-5 had been abolished and catatonia is considered as a trans-diagnostic specifier, moreover in ICD-11 certain symptoms can be added as symptoms specifiers to an existing diagnosis of primary psychotic disorder.

Our aim was to establish a new trans-diagnostic, dimensional scale to assess the most important symptoms amongst patients with psychotic disorders. This scale is meant to represent the long-term clinical presentation and not a cross-sectional picture of a current state. We believe that long-term trajectories of these symptoms may be more connected to underlying biological features, such as genetic load (i.e. polygenic risk scores) and imaging results than the currently used diagnostic criteria. We think it is very important to create a tool, which is straightforward and short enough, so can be realistically used in everyday clinical work. This could provide important real-life data, which give us information about our patients from a different angle than the currently used diagnostic systems.

We have created the CPAN scale based on the current symptom specifiers of ICD-11 and the Clinician-Rated Dimensions of Psychosis Symptom Severity, which is an “emerging measure” for DSM-5 and also took into consideration our own clinical experience.

The new tool measures 4 symptoms (catatonia, psychosis, affective symptoms and negative symptoms) on a scale of 5 (0-4). We have also put in specifiers to be able to characterize patients more precisely, and output measures (suicidal risk, functionality) to open the way for further analysis.

We tried to establish a novel symptom scale to help assessing patients with psychotic symptoms in everyday clinical work. Our plan is to test the validity of CPAN in the near future.

First episode psychosis (FEP) is the first manifestation of psychotic disorders lasting at least one week, but not longer than 2 years, causing personal suffering and decreased functional outcome of patients. The early intervention in FEP is crucial. Published results on early intervention programmes indicate that during the first 5-10 years relapse prevention and functional outcomes can be improved and mental health care costs can be reduced, compared to treatment as usual.

Our objective was to examine FEP patients at the Department of Psychiatry and Psychotherapy. Our aim was to create a homogeneous sample and identify factors that can help in early differential diagnosis and therapy. Our goal was to compare the neuropsychological performance and MRI results of patients and healthy controls.

Male and female inpatients hospitalized at our department due to a first psychotic episode and consenting to participate were included, since 2019 October. Cases with drug induced psychosis and organic background in the etiology of the psychotic episode were excluded. Male and female healthy controls were matched by age and education. Including healthy controls is still in progress. The duration of the project is 36 months, 24 months for recruiting patients and healthy controls, 12 month for analyzing data. The investigation includes detailed clinical, neuropsychological examination (baseline, 6th, 12th, 18th, 24th month) and MRI (baseline and in the 24th month).

Forty patients and sixteen healthy controls were included. 60% of the patients were rehospitalized due to relapses. Neuropsychological tests (RBANS, faux pas, Baron-Cohen eyes test) indicate cognitive dysfunction compared to healthy subjects. Using resting state fMRI second level analysis we found alterations in thalamo-cortical connectivity. We found significant differences in the connectivity of the thalamus and frontal lobe, postcentral gyrus, insula and cerebellum.

Our FEP research, although limited by the COVID-19 pandemic, shows promising results that can help in better understanding of the underlying factors of psychotic disorders.

Anti-NMDAR encephalitis is an autoimmune disorder, characterized by neuropsychiatric symptoms, such as mood instability, psychosis, catatonia, dyskinesia, seizures and vegetative lability. Psychiatric symptoms usually occur in the initial phase, therefore almost half of the patients are first observed at a psychiatric unit, however in later phases the patients’ condition often show progression with the characteristic neurological symptoms, such as perioral dyskinesia and seizures. Although, early recognition and treatment is essential to reach good outcomes, delay in the diagnostic process often happens due to the unspecific early symptoms and the lack of knowledge of this disorder amongst psychiatrists.

Moreover, there are cases, where neurological symptoms do not appear, which can lead to diagnostic failure and mismanagement of these patients. Since anti-NMDAR encephalitis is a rare condition, it is important to treat such cases in specific centres, where sufficient knowledge and multidisciplinary approaches are available.

Our aim was to gather all patients’ data treated with anti-NMDAR encephalitis at two departments (Neurology and Psychiatry) of Semmelweis University. We wanted to analyse psychiatric manifestations of the disorder in details and follow these symptoms long term, with special interest on the cognitive symptoms.

One of our aims was to follow-up these patients and measure antibody titres in their serum, to be able to asses, whether there was any association between prolonged serum positivity and cognitive impairment.

We have retrospectively analysed data of previous cases and prospectively followed up recently hospitalised patients.

Neurocognitive assessment had been conducted by the same psychologist, all the patients were followed up by the same interdisciplinary team, including a neurologist and two psychiatrists. Laboratory tests (autoimmune antibody essays) were conducted by the Immunological Laboratory at Semmelweis University.

Altogether, 13 female patients were treated with anti-NMDAR encephalitis in the past ten years at Semmelweis University. All of them received plasma exchange, iv. steroids and azathioprine. 8 out of the 13 needed ventilation and intensive care treatment. 2 of these patients have mild psychiatric symptoms as residual symptoms, and 1 of them is still in the recovery stage, currently experiencing mild cognitive symptoms.

Only two patient had ovarian teratomas out of the 13, which is a lower number than expected from previous studies.

4 out of 12 had positive antibody titre at follow up, one patient is still at recovery stage, however her antibody titres are still very high.

Semmelweis University is one of the largest centre treating patients with anti-NMDAR encephalitis in Hungary. We had altogether 13 patients in the last ten years, with very good outcome, since all of them recovered, although 2 have residual symptoms.
